Hard boil eggs, boil potatoes (good Jersey new potatoes for example); slice the tats on kitchen paper so they’re nice and dry, and let them sit so they’re cold. Fry them gently in butter and oil until nice and golden. Add a lot of double cream, salt, pepper and a sprinkle of nutmeg. Let it cook in for a bit. Slice the eggs over it at the last minute, mix gently and serve with salad.
